Town staff warns of major costs after culvert review; council to get detailed plan in 2026

Danville Town staff described a newly required stormwater asset-management effort that will inspect, map and assess roughly 33–36 culverts the town recently accepted from the county — work staff said could cost in the low millions.

Staff explained the legislature clarified responsibility for small drainage structures located inside municipal boundaries, placing maintenance obligations on municipalities without providing a matching funding mechanism. As a result, the town identified about 33 culverts to evaluate, and staff said they have found additional structures that require confirmation.

Public works staff cautioned council that some culverts date to the 1920s–30s and are constructed of aged concrete; photos will be shared with council once the assessment is complete. "We're looking at probably 2 to 3,000,000," staff said as a preliminary range, acknowledging that costs could be higher depending on condition and complexity. Staff said the work will be prioritized by condition to manage cost and that the town’s stormwater utility gives a vehicle to fund a long-term, 20-year program.

Councilors raised concerns about the scale and timing of repairs, whether existing scheduled projects were removed by higher authorities and the need to alert state legislators. One councilor urged notifying the town's state representatives about the impact the legislative clarification could have on local budgets.

Town staff committed to completing the inspection work in 2026 and returning with dollar estimates and a prioritized plan. The council did not authorize funding at the meeting; the discussion concluded with staff agreeing to share assessment results with county partners and the council.

Next steps: staff will finish the culvert assessments, produce cost estimates, and report back to council with a prioritized plan and financing options.
